My 4yr old son has HFA. He is very sensitive to noise and hates crowded environments. I recently moved him to a School with a base (special education classroom), sensory room and closed classrooms as I thought he would benefit from these things. This School is out with our village. I did have in our local school and had small concerns but nothing to major. Had to push for use of visual aids social stories. I am finding I am having the same battles with new School. They are actually more resistent to use visual timetable with him. I am worried that I am adding more stressed into the family by taking him out of our community and it would be calmer to walk to School and have friends around our home. But my question is what do people think of closed classrooms versus open planned. Base unit versus special ed teacher in normal classroom?.
